Is the Liquid Biopsy Really Accurate?

In the fight against cancer, early detection is vital. The newest field of research in cancer detection is the area of blood tests for cancer diagnoses. Several bio-tech companies are currently working on tests that pick up signs of cancer before a person even has symptoms. Experts agree that this kind of sensitivity is years away and that more research needs to be done

Recently, Pathway Genomics, a company that markets and a blood test called "Cancer Intercept Detect and Monitor" launched their test in September 2015. Initially there were claims that it could detect tumors before symptoms appear. Check out this video on the science behind these early tests and why, despite the appearance of early success, the technology isn't quite there yet
